This view is effectively obsolete, although it is probably still in active use by CWE consumers.

In Summer 2007, NIST began using this set of CWE elements to classify CVE entries within the National Vulnerability Database (NVD). The data was made publicly available beginning in 2008. In 2016, NIST began using a different list as derived from the "Weaknesses for Simplified Mapping of Published Vulnerabilities" view (CWE-1003).
